LLM Novel Translator (BYOK)

About

Translate web novels using Large Language Models (LLMs). Maintains character names and terminology consistency across chapters of the same series through an auto-generated, self-updating glossary.

⚠️ IMPORTANT DISCLAIMER: BYOK ONLY ⚠️
This extension requires you to bring your own API key from a supported LLM provider (e.g., OpenRouter, OpenAI, Gemini, DeepSeek). It provides no free translation services. You must purchase credits or enable billing directly with your chosen provider.
Why BYOK? Because you pay exactly what the AI costs, and know exactly which model you are getting.
  👉 No middleman pocketing the difference by selling you a "$20/month plan" or "1500 credits package" that's actually $5 worth of tokens.
  👉You're not selecting a "SuperTranslationModel MK.III" that's actually just a tiny 4B model under the hood.


🔒 Privacy First
  🛡️ No Proxy Server: Your API requests go directly from your browser to your chosen AI provider. We never see what you're reading, which sites you're visiting, or the content you're translating—because we're not in the loop.
  💻 Open Source: The full source code is available on GitHub. You can inspect the full processing logic and prompts being used, or fork the repository and build your own version if you wish to modify the LLM prompts or any aspect of the extension.
  🚫 No Hidden Fees: Since there is no central server to maintain, there are no subscriptions. You pay your AI provider directly for the tokens you use—and you're not subsidizing other users' free tiers.


✨ Key Features
  🧠 Context-Aware Translation: Uses advanced LLMs to translate text while preserving narrative flow and nuance.
  📚 Smart Glossary System: Automatically identifies, generates, and updates a glossary of terms (character names, locations, cultivation ranks) to ensure consistency throughout the novel.
  ⚡ 1‑Click Translation: Effortlessly translate from the popup—simply open the extension and click the translation button, it will replace the text on the page once the translation is complete.
  🎛️ Model Freedom: You are in control. Choose Claude 4.5 Sonnet for increased quality, or DeepSeek V3.2 for a cost-effective reading experience.
  🌐 Multi-Language Support: Capable of translating between various language pairs supported by the underlying LLMs.


💸 Cost Control
You have full control over your spending. Whether you want to translate a few chapters or binge a thousand, the cost depends entirely on your chosen model and provider.
  💎 Ultra Quality: Use top-tier models like Gemini 3 Pro or Claude 4.5 Opus for the absolute best results.
  ⚖️ Balanced Performance: Choose models like Gemini 3 Flash or Grok 4.1 Fast for excellent quality at moderate cost.
  🏷️ Economical: Use efficient models like DeepSeek V3.2 or GPT-5 Nano for a fraction of the cost.
